While we all agree pistachio is the way to go, we couldn't agree on who serves the best version, newly opened Grom or L'Arte del Gelato.L'Arte has our resident Sugar Rush experts Kathy Chan and Robyn Lee in its corner, while Raisfeld and Patronite—from the sound of what they wrote—and I all tend to lean toward Grom. (Let it be noted that I am a cheapskate, and my willingness to pay Grom's exorbitant prices is only a testament to how good it is.) For final judgment we turn to the serious eater out there. Let us know what you think in the comments.
